Ok this is the best I have found so far as a color chart http://www.modifiedlife.com/1988-ford-thunderbird-car-stereo-wiring-diagram/
But for the rear there is no green wire on the harness and why in the hell would I hook up my front speakers to the ground wire
I've installed a few stereos but not like how this is
Also I have some speakers that will go in and I took a look at the stock 6x9's they have 4 wires going to them wtf
Why is this car like non other lol
premium sound. Google it.
I hate Ford Premium sound systems, lol. My 90 SHO had it.
Yea it seems like a nightmare lol
Found somthing else that exsplanes it a little bit but I don't have a eq or factory amp
Now I know why this car has the factory tape player lol
I always just cut the connectors off, stick a 9 volt to the two wires with and without stripe till I get sound. a lot of the time I just run new wires to the doors and dash. real easy if you want to revert back to a factory setup later.
Yea seems the ez way is to run new wire
so is everyone saying that the best way to put a new stereo in a car with premium is to rewire and eliminate the stock stuff completely, what do you do with the factory EQ
I've never actually seen a factory eq that worked properly. I always find them with toothpicks jammed into the power on/off button.
I personally believe its up to who owns the car. I actually quite enjoyed the stock premium sound with eq on my crown vic. I did eventually throw a cd player in it though. but the stock speakers and everything sounded fine, and I just ran a tape deck adapter to play music off of my phone.
